INSULATOR FITTING. i

Appncation inea' March i, 1923. semaine. 621,975.

This invention relates to fittings or hold- I ing devices forusein connection with insulators such as are shown in my prior design Patent :tt-56,262, Sept. v14, 1920.

i l,economical to manufacture and which shall be of improved constructiomeasy to install and strong and efficient in operation. This invention 1s exempliiied inthe combination Vand arrangement of parts shown in ,the accompanying drawing and described in.

t-he following specification and itis more particularly pointed out in the appendedclaims.

In thefdrawing:

Fig. 10 is a section online 10-10 oi Fig. 7 Fig. 11 is a'section on line 11-11 of Fig. 8. Fig. 12 is a perspective View otra detail. As illustrated in thev drawings the numeral 10 designatesa pair of insulators connected in series. y

may ot course be included 1n the string. The

Any number of such insulators insulators are provided with crossed transverse openings 11 through which yoke members 12 are threaded. These yoke members may be rounded on their tacos which engage the insulators as shown at 13 Fig. 6, and flattened on their outer faces as shown at 14. This gives a fitting surface where the yokes bear upon -the insulator andpermits a close bend at the endsot the yoles to form hooks 1 5. The hooks are secured to supporting bars 17 or to connecting links18 yfor connecting the parts ot the insulator string to one another or to a supporting member. The

supportingr bars 17 are Curved in section as -l shown in Fig. 3, and have slots 18 cut there- A'iii'to, facilitate Qengagementwith the hooks 15. At the endsy f the slots 18, the conneetor. bars are yslitted. erosswise .tofprovide holding. bars'19l engaged by thev hooks;l 15.

It willbe apparent that the various portions .of thelittingniay` formed by automatic machinery almost entirely. such yasv-punch presses or similarmaclnnes. lthus providing ,v very economicalv methods of manufacturing.

The parts areeasily installed since the connectionsare made by simply hooking the `parts and inserting lthebolt 23?. 'Ihe stren gth and reliability of the connection is'greatly increased by the retainer bars '24 lwhich prevent unbending of the hooks 1,5.

In the formof the inventionshown inFigs. 7, 8,. and-9, the bolt 23 is omitted and spring plates 25 held byrivets aresubstituted for the retainer plates 24.. In place ot' the support- Ving links `17 and bolt 21, 'a sheet metal elevis V27 is used, the clevisbeing provided with tongues 28 which retain the hooks 15in posi-V tion. The t'ongue'sf28 are bent outwardly as shown inthe lower portion of Fig.'7 to per-2 mit assembly of theparts. but when the parts are together the tongue is bent inwardly as shown in the upper portion of Fig. 7 which prevents disconnection of the hook 15. The manner of assembling the parts shown in Figs. 7and 8 is similar to Figs. 1 and 2.

that described in Iclaim:

1.1'y Connector-sf for insulators comprising a pair of yokes arrang-ed to extend through openings inra pair of insulatorsl toY be conc .wformfhooks ,andiv plates `overlapping saidv insulators and having openings therein for engaging said hooks to join 'said /insulators to each other. Y n

2. A connector for ,aiiinsiilator having a groove therein, said connectorcomprising a I i yoke positioned in said groove and having an outwardly and backwardly' toform a hook,

4 outwardly bent hook on' the end" thereof4 and ai linkihaving .transverse slits therein providving transverseV bars, said bars being bent in Voppositedirections to provide anengagement 'for'said hook, one of said barslying within `the bight osaid hook and the other engaging the outer iace'of the free end of said hook.

Connecting means for aipair of insulaktors vcomprising [yoke 'members threaded 'throughfperforations in each of said insula-V tors, said yoke members having the opposite Y endsv thereof bent to iorm hooks,sheet metal connector links l'having openings Atherein `forming eyes into which saidhooks arelinked, said connector links bridging the .space between said insulators at opposite sides of'said insulators and a. transverse connector vfor vholding said'linksfagainst the sides of said insulators. Y l

' 5. Connecting meansfor appair ofrinsulators comprising ayyo'ke member connected with each oi.- said insulators and having its ends bent backwardly toform' hooks, a pair ofV channel shaped links connectingsaid hooks and having transverse slits `therein to pro' vide ay pair of adjacently disposed bars for engaging each'of saidhooks, said bars being spaced relative to eachother so that they pass ne'cte'd; the en'ds of. said yokes beingxbentto 1 '3.*Afsconnectorfor anv insulator having ar on opposite sides of the free end of the hook whenl theparts are assembled.

`6. Connecting means for a pairof insulators having perforations therethrough, said connectingmeans comprising a yoke member .threaded through each'of said per-forations,

said yoke members having inner curved faces for engaging the insulators and having sub- Y Astantially flat outward faces, the ends of said -yoke member being bent outwardly and backwardly to form hooks, channel shaped links Vfor engaging said hooks vto connect said insulators to each other and retainer bars eX- tending froin sidev to side of lsaid channel shaped links to hold said hooks from straightening. v
